UNITED STATES PATENT OFFICE.

GEORGE J. KELLER, OF OSCEOLA, NEBRASKA.

METALLIC LIFT-PU MP.

SPECIFICATION forming part of Letters Patent No. 418,191, dated December 31, 1889.

Application filed September 6, 1889. Serial No. 323,119. (No model.)

citizen of the United States, residing at Osceola, in the county of Polk and State of Nebraska, have invented certain new and useful Improvements in Metallic Lift-Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

`to the letters of reference marked thereon,

which form a part of this specification.

The invention relates to metallic liftpumps; and it consists in the construction, arrangement, and combination of parts hereinafter described.

Figure l of the drawings is a vertical section on the dotted line oc of Fig. 2, and Fig. 2 is a horizontal section on the dotted line y y of Fig. l.

In the drawings, A represents a top-covered and bottom-open cylinder with the uppipe a, through which the water passes to the outletor discharge spout, the apertured flanges ot a on the outside, the horizontal partitions t2-a3, and the vertical diametrical partitions a4 a4. In each quadrantal compartment and on the horizontal partitions a2 is arranged an upper hinged valve b, and on the partitions a3 are hinged the pistons C, carrying valves c, all of said valves opening' upwardly.

D are the piston-stems formed of metallic rods end-bent to form the hooks d, which work in vertical slots ai of the cylinder and support the hinged valves C. The latter fall by their own gravity, and are raised by the hooks d, the operation of Ysaid valves being the same as in any ordinary lift-pu mp, except that the valves c turn in the arc of a circle, and the cylinder A is curved Vat a6 to correspond. All the compartments open into the superposed chamber E, whence the water is forced up` the discharge-pipe a, while the stems D may be connected with operative mechanism, so as to actuate the pistons and make them work together or successively. The lower part a7 of the cylinder rests on the bottom of the well, and the water enters there through the slots a or through side perforations.

What I desire to protect by Letters Patent 1s- The combination, with a top-covered cylinder A, having an upper chamber E, with the up-pipe ct, of the horizontal partitions a2 a3, the vertical partitions c4 a4, the slots a5, the curve as, the valves b on the partitions a2, the hinged pistons C, carrying the 11p-valves c, a'nd the rods D, having the hooks d at the lower end, whereby two or more pumps may be operated separately or together in the same well, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
